| When compatible with the generic version, nodes must list the |
| SoC-specific version corresponding to the platform first followed by the |
| generic version. |
| |
| - reg: Base address and length of the I/O registers used by the UART. |
| - interrupts: Must contain an interrupt-specifier for the SCIx interrupt. |
| |
| - clocks: Must contain a phandle and clock-specifier pair for each entry |
| in clock-names. |
| - clock-names: Must contain "sci_ick" for the SCIx UART interface clock. |
| |
| Note: Each enabled SCIx UART should have an alias correctly numbered in the |
| "aliases" node. |
| |
| Optional properties: |
| - dmas: Must contain a list of two references to DMA specifiers, one for |
| transmission, and one for reception. |
| - dma-names: Must contain a list of two DMA names, "tx" and "rx". |
| |
| Example: |
| aliases { |
| serial0 = &scifa0; |
| }; |
| |
| scifa0: serial@e6c40000 { |
